Your Complete Comparison by Greentastic Pty Ltd
As solar power continues to grow across Melbourne and regional Victoria, more homeowners are choosing to add a solar battery to maximise energy savings, protect against blackouts, and reduce reliance on the grid. But with so many energy storage systems available — from AlphaESS to SolaX, Dyness, ESY, and NEOVOLT — choosing the right battery can feel overwhelming.
At Greentastic Pty Ltd, we install the most reliable, high-performing, and future-ready solar batteries in Australia. This guide breaks down each major system to help you make an informed decision for your home.
Why Solar Batteries Matter in 2025
Today’s energy landscape is changing fast:
- Peak hour tariffs are rising
- Grid outages are more common
- Solar feed-in tariffs are dropping

✔ Reduce electricity bills
✔ Stay powered during outages
✔ Become less dependent on the grid
✔ Increase property value
✔ Build long-term energy independence
